These pistons are the same as YZ125 pistons which are cheap so I would replace it. I would flush the crank and bottom end bearings with WD40 a couple times and blow it out with compressed air. I would then pour some extra premix oil into the crank area including down the oiling holes in the cases.

That sounds promising! I am not sure what you mean by non-tm though. Do i just mic the shaft to find out size?
